I'm modifying my html template to include the 'master index' page and I can't get good output for it. Namely, html output doesn't get produced at the masteridxgroup & masteridxelement level. Here's my code for the masteridxelement, which is the same code I used for the idxchildelement:

I thought that recycling code in this case would work, but I'm not getting any html output, including any errors that help me find a bad variable. Any suggestions? Thanks!
